Amazon ELB CNAME 记录不起作用
我已经在 ELB 实例后面设置了 EC2 基础设施，并使用 ELB DNS 名称，一切都按预期运行。现在我想使用 CNAME 条目将主项目域的子域转发到 ELB DNS 名称。我大约 12 小时前这样做了，但似乎不起作用，我不知道为什么。子域名无法解析。
这是昨天从我的 DNS 提供商处理的 DNS 条目，没有错误：
@ IN A 111.111.111.111
localhost IN A 127.0.0.1
mail IN A 111.111.111.111
www IN A 111.111.111.111
ftp IN CNAME www
beta IN CNAME myelbnamehere.eu-west-1.elb.amazonaws.com
imap IN CNAME www
loopback IN CNAME localhost
pop IN CNAME www
relay IN CNAME www
smtp IN CNAME www
@ IN MX 10 mail
使用 nslookup，所有子域和主域都能正确查找，但 beta.domain.com 却不能。我收到“** 服务器找不到 beta.domain.com: NXDOMAIN”
我做错了什么？我需要等待更长的时间吗？当我直接使用 ELB DNS 名称时，一切都按预期工作。
当我在我的提供商 DNS 服务器上执行 NSlookup 时，CNAME 得到解析，但看起来任何其他 DNS 服务器都无法找到子域，
提前致谢
I have set up my EC2 infrastructure behind an ELB instance and by using the ELBs DNS name everything works as expected. Now i wanted to forward a subdomain of my main project domain to the ELBs DNS Name with a CNAME entry. I did this about 12 hours ago and it doesnt seem to work, and i dont know why. The subdomain just cant be resolved.
This is the DNS entry which was processed from my DNS provider without errors yesterday:
@ IN A 111.111.111.111
localhost IN A 127.0.0.1
mail IN A 111.111.111.111
www IN A 111.111.111.111
ftp IN CNAME www
beta IN CNAME myelbnamehere.eu-west-1.elb.amazonaws.com
imap IN CNAME www
loopback IN CNAME localhost
pop IN CNAME www
relay IN CNAME www
smtp IN CNAME www
@ IN MX 10 mail
Using nslookup, all the subdomains and main domain gets looked up correctly, but beta.domain.com doesnt. I get "** server can't find beta.domain.com: NXDOMAIN"
What am i doing wrong ? Do i need to wait longer ? When i use the ELB DNS name directly everything works as expected.
When i do an NSlookup on my providers DNS Server, the CNAME gets resolved, but it looks like any other DNS server cant find the subdomain
thanks in advance

如果这是来自您的 DNS GUI 的精确引用，那么您似乎缺少
beta条目中的尾随.。它应该是：如果没有
.，它将被解析为：这当然不存在。
If that's an exact quote from your DNS GUI, then you appear to be missing the trailing
.from the entry forbeta. It should read:Without the
., it'll get parsed as:which of course doesn't exist.
